PURPOSE:To enable the use of a low-priced core and shorten the diversion cycle of the core by winding a web winding starting edge part around the core formed of a tubular body made of material unaffected even in contact with water while spraying web bonding liquid to the web winding starting edge part, and pulling out the core after winding the web to the product length and drying a web wound body. CONSTITUTION:A core 2 with its outer diameter approximately equal to the inner diameter of the center hole of toilet roll paper is formed of a tubular body made of material unaffected even in contact with water. A shaft body A with the core 2 mounted to a common shaft is positioned at a web winding part 12 in such a way that the core 2 corresponds to a web Q, and a web winding starting edge part is wound onto the core 2 while spraying web bonding liquid to the web winding starting edge part from a nozzle 19. After winding the web around the core 2 by the product length, a web wound body is discharged onto the bearer 17 side from a web winding part 2, cut off by a web cutting device 16 and dried on the belt conveyor of a drying device, and the core 2 part is pulled out of the web wound body R in a core extracting process. |
